Directional Spool Valve H-4WEH25E6X/6EG48N9TS2K4 - Bosch Rexroth R901026079

The pilot-operated H-4WEH25E6X/6EG48N9TS2K4 spool valve switches flows up to 700 l/min in size 25. Pilot oil is supplied externally and returns internally, while the solenoids work on 48 VDC.

Benefits

• Up to 700 l/min flow at 350 bar maximum operating pressure
• 48 VDC supply voltage, matching plants built on that level
• External pilot oil supply with internal pilot oil return
• Three switching positions to spool symbol E across four ports
• ISO 4401-08-08-0-05 connection diagram, NBR seals for HL hydraulic fluid
• Connector, 3-pole (2 + PE) to EN 175301-803, weight 18.7 kg

Application

The valve drives large cylinders in presses, lifting gear and rolling lines whose flow demand is far above size 10. It mounts on a size 25 subplate. Because pilot oil comes from outside, the pilot circuit has to stay pressurised even when the main circuit is unloaded.

Manufacturer
